SHUTTLE-BLOCK PIN.

Application led May 25,

To @ZZ whom t may concern Be it known that I, FRANK H. S'rnrsoN, a citizen of the United States, residin at Methuen, in the county of Essex and tate of Massachusetts, have invented certain new and useful Improvements in Shuttle-Block Pins, of which the following is a specification.

This y invention relates to shuttles for looms, and is peculiarly adapted for such shuttles as are used in weaving worsted yarn or thread, which has a veryA strong ten-y dency to cut metal. A

-I am aware that pins of metal, preferably steel, have been used in connection with threading blocks of shuttles for the yarn to turn aroundv at 'right angles "so that the thread, which starts to unwindv and play out along the longitudinal axis 'of the shuttle, can pass out at right angles thereto through a suitable shuttle eye. f

I am also aware that a metal roller Vhas been substituted for this pin, and I am further aware that a roller of porcelain or other wear resisting material has also been tried. in this position but set atan angle.

Where worsted yarn or thread is used, it will cut a steel pin or steel roller, and where a porcelain roller is used, the yarn will either catch between the ends of the roller and its supports or must be protected by means which are generally inadequate from the tendency of the roller as it turns to catch the yarn in such places.

My invention preferably comprises a porce-Y lain tube or other suitable member of wear resisting material supported from the top by means of a metal pinwhich is passed through it and thence into the under part of the top of la threading block, such wearl resisting member being fixed to such a pin.

By so locating and fastening my wearing member, which is preferably a porcelain or glass tube, with one end fixed and the other end free, a certain amountv of vibration is allowed which helps to prevent cracking and breaking. Besides this, there is no loose nor rolling part torwear unevenly, to rattle or break. 4

Fig. 3 is a sectional elevation on the line 3-3 of Fig. l looking from the direction of the arrow, the wood being shown in section and the metal not in section showing my preferred form of shuttle block with my preferred form of pin in position in a shuttle.

Fig. L is an elevation from the front,'and Fig. 5 is an elevation from the side of a shuttle block of slightly modified form with my preferred form of pin in position.

Fig. 6 is a sectional elevation showing the adjoining parts of a pin and shuttle block such as shown in Figs. 4, and 5.

Fig. 7 is; a sectional elevation of a slight modification of the relation between my pin and shuttle block. l

Figs. 8, 9 and 10 are sectional elevations of variations of my wearing member.

Fig. 11 is a vertical sectional elevation as from the right of a shuttle, or as from the direction of the arrow on -line 11-11 of Fig. 1, showing the application of my compound pin to a shuttle in a different manner.

Figs. 12 and 13 show in sectional elevation other variations in the application of my compound pin.

Fig. 14 is a vertical sectional elevation of a compound pin of my preferred construction.

In the drawings, A represents'a shuttle having the usual delivery eye 11 in the wood and suitable thread guiding recesses, indicated by 12, connecting therewith. 13 represents a block recess in which is located a threading block N, the top of which is flush with the top v10 of the shuttle. This is shown as having the usual projection 30 and as having the usual fastening hole 28 through which passes horizontally a screw or bolt 14 to hold the block in position.

This threading block has a threading chamber C, and in a preferred construction, shown in Figs. 2 and 3, has at the back a locking guide 27 andis formed with a guide' plate 20 which .extends into the threading chamber and at the back terminates in a guide hook 22 which extends downl below or overlaps the locking guide 27. Prefera'# bly it also has at the front a thread trapping rim 21, and it has the usual guide' horn 23 eol which guides the yarn down into the threading chamber.

A little behind and adjacent to horn 23 is a boss'l9'in which is a wearing member recess 25 from which extends upward through the top of the threading block a pin hole 26. 'A- pinr having a head 38 extends up through pinhole 26, being driventhereinto or soldered therein by solder 37 so thatit is fixed in position.

Preferably also, shuttleeye ll and otherv partsare so placed that the normal tendencyl of the threadl is to run about the middle lpart oftubef B,.

In Figs. l and 5, I show a threading bloclrf H similar. in mostv respects to that shown fattNl but..,without the overlap 27, and instead of a protecting wing, such as 24,
